(l) 00:46:269 (1) - everything in this section seems to be following around 2x ds, so lowering this to 1.6 on a downbeat feels really out of place - i'd just suggest bumping it up to 2x to be consistent with everything else
(l) 00:48:850 (1,2) - could do something like this to prevent the slight overlap on 00:48:527 (4,2)? i think this flows a bit better too~ 
01:01:430 (4) - you might want to change this into 1/1 circle here instead to give the player some rest otherwise having continues rhythm chains can be very draining
(l) 01:01:753 (1,2,3) - flow here is a bit weird with how the reverse slider is angled, maybe ctrl + , this to make it parallel to 01:02:398 (1)?
(l) 01:52:237 (1,2,1,2,1,2,1,2,1,2,3) - rhythm on the ending section feels a bit hard to understand, mostly because the most intense sounds (like on 01:52:721) are on sliderends
since you didn't map these in the insane (i missed that earlier :p), i'd just remove all rhythm that isn't in the insane~
